Some British researchers have found out how to defeat (some of) the Chinese Internet-censoring infrastructure: The keyword blocking system doesn't block packets. Instead it sends RST packets. Which you needn't heed. Nice.

I'm no fan of EczemaScript but the recent Westpac/Virgin mess convinced me that scripting in the browser is not necessarily bad - as long as I control what runs where and when (hence I use NoScript and deny all scripts everywhere except where I know the code).

Yesterday I mucked around with making the local TV guide website bearable - all I really want to see is the innermost table of actual information, minus all the square acres of blinking advertisements and similar drivel.

Upgraded to Firefox 1.5 (actually painless, very different from past experiences), installed the newest (0.6.4) Greasemonkey, found a script that claimed to fix that mess but which was too ugly by far, rewrote it to suit my prefs, done.

I learned a lot about Javascript and DOM (and also where Greasemonkey sucks) than I ever wanted to, but that's fine.

Today I thought about tackling the Virgin problem, but found out that Joel Hockey has already written a nifty simple small script that gives you text-based password entry back (without removing the silly buttons, should you be stupid enough to want them). Thanks, Joel!

But it didn't work. My stubbornness has few limits (and the weather was not flyable today), so I learned still more about JS and GM and the DOM, especially about the recent paranoia that badly affect the new Greasemonkey and wrecks most of the nice things about DOM and JS (if there were any in the first place).

In the end I fixed Joel's script (and sent it back upstream) and am now quite pleased with my army of greased monkeys.

Yesterday was my birthday. It rained.
Quite a few people sent their wishes, and I'm happy about that.

My kid didn't and I'm not happy about that.

Sometimes I need time off the computer stuff and deal with tangibles. Playing around with house-related things serves very well here, and most of the time iff I get started on a project, it ends up between fine and perfect.

Looks like the gods in charge of the weather also don't believe in queens, or rather believe in first soaking and then blow-drying.

Saturday it rained/drizzled/rained/blew, and Sunday it simply howled. Nevertheless we had a nice weekend - just a camping weekend without flying.

I believe neither in god nor any sodding queen, but whatever it takes to get a public holiday! (coming Monday)

I and a group of Like-Minded Loonies are going out to killarney tomorrow afternoon, for a nice cold, maybe flyable long weekend. Unfortunately the forecast is dreary enough that the invocation above seems justified...unless god also doesn't believe in queens.

I rebuilt my backup-and-music box recently, because the case was ugly and because I needed to fit another disk for online backup.

I had a Sun 811 case lying around, and another similar to a 411. Neither would take the Epia motherboard, PSU, dvd burner, two 3.5" disks and a 20x4 lcd, but together they can throw off the yoke of conformist PCism! ahem

So I cut out the plastic top of the 811 and riveted the 411 onto it, which gives me space for the drives. A face for the open rear end of the 411 was cut from the cannibalized pieces of my Sony stereo junk and hot-glued in. The frame for the HDs is an old cut-up drive bay, and the support for the burner is a piece of sheet metal that I riveted in (hot-glue isn't strong enough and I didn't want to use expoxy for no reason at all).

The front with the lcd got a painted fascia (balsa) and the IR sensor was mounted internally this time.

After a shitload of further surgery on the cases and innards I ended up with this pleasant look.

But you can't see the rear in that photo which is good. None of my small ATX power supplies would fit without totally rebuilding the thing (not-so-perfect an idea as I'd basically have to strip all insulation off, then resolder half the high and low voltage connections and cram all the resulting mess into the franken-case), so I started looking at DC-DC PSUs. Like this one. Which I did eventually buy, thinking "the 90W/145W peak PSU I have used so far, so this 200W thing should do nicely". Cost me about us100 (with a 9A AC-DC external brick and shipping). Little did I know, and for that matter, too little effort did I spend on research. Plug it in, fire up, works - somewhat: now I get loads of noise on the audio out connection. Not just mains hum but all kinds of activity-dependent crap as well. This is when I started doing the research I should have done before. It turns out that loads of people hate the PW-200-M for being a crap piece of equipment. First, it's nowhere near 200W, and some other speciality PSU manufacturers have accused the makers of shoddy lying advertising. The 5V rail sagged under the load of my two disks down to less than 3V at times. The 12V line is not regulated, so iff you're not using a regulated brick you'll fry your gear (especially the carputer people hate it for that). The smoothing caps are not exactly large at 390-1000uF. (But the form factor rocks, which is why I bought it...) Tried pretty much everything non-destructive, like powering only the board from the PW-200-M, trying different 12V supplies to verify the noise is coming from the PW-200-M etc...but no joy. It may be useful for really low-power scenarios where one doesn't care so much about power quality (i.e. non-audio application), but for me it's junk...Bugger. Back to square one: normal PSUs don't fit. Most high-quality DC-DC PSUs like the Opus gear won't fit or require 19V like the DC2DC converters.... So for the time being, I plopped my normal small ATX PSU like an outboard motor behind the box...with some shielding and extra grounding it doesn't affect radio reception too much. sigh [ published on Wed 07.06.2006 16:22 | filed in | ] It does get a bit cold at nights now (+5°C last few days on the coast, with frost inlands) but the days are still nice at up to 22°C and, predominantly, sunny. That's the kind of winter I like nowadays. Some flying pics; last weekend we were rushing from site to site and mostly parawaiting as in the first pic. This weekend wasn't lots better but a bit: Saturday was blown out, Sunday was very south but still good enough for Beechmont. I got an hour of airtime and took some pics of Marty and Phil. I've also got two short movie clips (taken with the digital camera, so they suck) of Rob at Killarney two weeks ago and one of Phil launching at Beechmont today. [ published on Mon 05.06.2006 01:00 | filed in | ] My backup tape stacker died recently, so I had to look for alternate cheap backup solutions. Goodbye Amanda! snif Recent tape drives being prohibitively expensive, I went for two more 200gb disks, one for the living-room machine (aka. tosspot) and one for an usb enclosure and transfer via sneaker-net to the office. So far, so good. The choice of available software, however, and my paranoia re backup storage have an intersection close to \epsilon: backuppc doesn't encrypt. boxbackup does, but is a bit rough and needs loads of certificates to get anything done. On a comparison page about boxbackup I found a link to duplicity which has a very nice feature set which meets my ideas of backup pretty nicely: • Everything happens on the client, the server only needs to give scp/ftp/rsync/s3 access. • Symmetric or asymmetric encryption, encrypt-but-not-sign as well. • a way to do incrementals that shows deleted files, while still not needing anything but gpg and tar to restore (if you've lost the duplicity program). • Doesn't need to decrypt anything for doing incrementals, if you give it a little space on the local machine. However, it's got a fair number of minor problems as well. Quite some debugging and head-scratching and four bug reports later (one two three for duplicity, two with patches and one for rsync with a patch as well) I'm now set: a dumb rsync server with some disk behind it, encryption (but no signing) to my gpg key happening on the clients, the result of which ends up on the server. To do incrementals cleanly, a little unencrypted space (--archive-dir) is set aside on the clients, where duplicity can store some hashes and other info of the files it's backing up. I still don't like python much but I'm at least reaching that debugging-and-mini-maintenance-hacking level. Syntactic whitespace sucks.

One of the fringe benefits of the recent trip to Austria was that Werner Koch gave a keynote speech at the conference I was attending to, we had a chat and exchanged signatures (surprise, surprise; opportunities like that...). That has catapulted my paranoia ranking up a fair bit (from about 23500th place). The newest analyses: by Henk Penning or Jason Harris No comprendo? It's all about a type of modern voodoo, oddly-clothed weirdos sitting around in pubs mumbling numeric incantations to each other and the result of this worship of mathematical concepts. In short, not something normal people get excited about... but we're not normal and proud of it! grin [ published on Thu 01.06.2006 14:38 | filed in | ] What a lovely read: "Emotional balance: The sniper must be able to calmly and deliberately kill targets that may not pose an immediate threat to him. It is much easier to kill in self-defense or in the defense of others than it is to kill without apparent provocation. The sniper must not be susceptible to emotions such as anxiety or remorse."

Christmas as in "Christmas 2005".

After a measly 6 months enroute and with the outside paper-and-plastic tube in a battered and fucked up state, but it arrived. From the looks of it, the postal idiots took the 'fragile!' note as an encouragement first to pack a few tons of junk on top of the tube and then to route it via Mars...

The last few weeks were character forming in Calvin's sense.

I have a new desktop at work: our boxes are leased, and every two years I have to move everything to a new box with new problems - as it's always the cheapest Dell crap you can buy. The assorted annoyances one has to put up with until the thing works reliably make me really hate the new hardware... this time it only needed one home-soldered Y power splitter, one ethernet card without slot bracket, a full move to the X.org X11 suite, a new kernel with loads of "new improved" shite enabled, and about two very long evenings to get things working (and I even convinced the crap i965 "graphics" chip on board to display at 1504x1128 on my 20" Sun CRT...).

My serverhousing box is still dead, the spare Ultra1 here has dumped its PSU, and I'm very much looking forward to the hardware twiddling in three weeks in Vienna. This is unfortunately not my serverhousing box:

This is my^Wthe Unix Guerilla's new backup-and-assorted-stuff-of-our-choice server. (That's my group of weirdos at work.) I've called the box "pachyderm", as it's got a nice thick-skinned case (and it replaces "elephant"). rho has already threatened me over the name, but I prefer it over his usual theme of female music artists. Getting debian installed and working on that fellow took some work, though: the sarge netinstall cd doesn't have a proper fdisk, only bloody partman, and that has a bug that makes it impossible to produce raid or lvm partitions - which I wanted, TYVM, given the 6x18gb discs. Also, partman is a menu-in-a-menu-after-other-menus-in-various-menus-and-menus-after-menus-followed-by-menus-piece-of-menu-SHITE, which sucks especially when you're working on a 9k6 serial console. I wgot an fdisk binary onto the ramdisk and got cracking (and totally circumvented partman and 50% of the installation procedure, but hey, it worked).

The last two weekends were so-so, the earlier one had a cyclone keep us from flying and this weekend I felt shitty and not in any mood for aerial fun. Rob told me that I didn't miss much, though.

In other news, some dimwit politicians are currently pondering a plan to require ISPs to provide only a violence-and-obscenity filtered Internet. Fortunately, there's voices of reason.

In still other news, I had a very bad day a few days ago, blew my cool in a mail to the flying club people I do infrastructure for, and also bought a few cool/nasty/elitist/geeky tshirts, among others the first one over there.

You want plussed addresses, as in yourbox+anything@yourdomain, reach you so that you can presort the junk?

Easy - if you have a Real Mail System. Like sendmail, postfix, exim, qmail or anything else that has come into contact with reality and the relevant rfcs. At worst it's one config entry for the server, at best it works out of the box.

If however you're stuck with MS Excrement Sewer, then you're either totally fucked (older versions) or you need this gem of hideously horrible bloated vbscript "event sink" thingie that sort-of-retrofits the capability. Because the Redmondian Loonieware Doesn't Do Wildcards or anything else that's even remotely useful.

I hate the corporate idiots who made the decision to dump our fully functional email system here @ work to bring in the MS dreck. I HATE YOU!
